Fortunately, you can help prevent contamination of the public water system due to backflow. If your irrigation system does not have a backflow prevention assembly, you need to install an approved assembly or device as required by your specific situation.
If your system does have a backflow device, ensure that it is in good working order by having it tested annually and the test results forwarded to the Canby Utility Water Department.
If a water hose is used to fill a pool, hot tub, pond, water feature, or even a wash bucket make sure it is protected with a hose bibb vacuum breaker installed on the faucet.
